There is no problems accessing the elements of enumerations with Jython.
The following was tested using Jython 2.7b1:

Jython 2.7b1 (default:ac42d59644e9, Feb 9 2013, 15:24:52)
[Java HotSpot(TM) 64-Bit Server VM (Oracle Corporation)] on java1.7.0_40
Type "help", "copyright", "credits" or "license" for more information.
>>> import java.util.Collections as Collections
>>> import java.util.Arrays as Arrays
>>>
>>> a = Arrays.asList(1, 2, 3)
>>> print(a)
[1, 2, 3]
>>> e = Collections.enumeration(a)
>>> print(e)
java.util.Collections$2@f48007e
>>>
>>> for i in e:
...     print(i)
...
1
2
3

Therefore the problem is either with LibGDX or (more likely) way you are
using it. Please post a minimal example that demonstrates the problem plus
the exact error message you get (I don't know LibGLX at all, but someone
else might, plus trimming it down to a minimal example may reveal the
problem to you).
